Zoology NEET
Classification of Animals
- Kingdom Animalia: multicellular, eukaryotic, heterotrophic
- Characteristics:
- Movement: voluntary or involuntary
- Nutrition: heterotrophic
- Body structure: multicellular
- Growth: growth and development
- Reproduction: sexual or asexual
Phylum Chordata
- Characteristics:
- Notochord (flexible rod-like structure) present at some stage
- Dorsal hollow nerve cord
- Pharyngeal slits
- Post-anal tail
- Classes:
- Pisces (fish)
- Amphibia (amphibians)
- Reptilia (reptiles)
- Aves (birds)
- Mammalia (mammals)
Phylum Arthropoda
- Characteristics:
- Jointed legs
- Exoskeleton
- Segmented body
- Classes:
- Crustacea (crustaceans)
- Arachnida (arachnids)
- Insecta (insects)
Phylum Mollusca
- Characteristics:
- Soft, unsegmented body
- Calcareous shell
- Foot, head, and visceral mass
- Classes:
- Gastropoda (snails and slugs)
- Pelecypoda (bivalves)
- Cephalopoda (cephalopods)
Human Body Systems
- Nervous System:
- Central nervous system (CNS): brain and spinal cord
- Peripheral nervous system (PNS): nerves
- Circulatory System:
- Heart: pumps blood
- Blood vessels: arteries, veins, capillaries
- Blood: transports oxygen and nutrients
- Respiratory System:
- Lungs: exchange oxygen and carbon dioxide
- Trachea: air passage
- Bronchi: air tubes
- Digestive System:
- Mouth: ingestion
- Esophagus: food passage
- Stomach: digestion
- Small intestine: nutrient absorption
- Large intestine: water absorption
Evolution
- Charles Darwin's theory of evolution
- Variation: differences in characteristics
- Heredity: passing of traits from parents to offspring
- Adaptation: changes in response to environment
- Natural selection: survival of fittest
- Evidence for evolution:
- Fossil record
- Comparative anatomy
- Molecular biology
- Biogeography
